Abstract: A method for occlusion detection on a target object is provided. The method includes: determining, based on a pixel value of each pixel in a target image, first positions of a first feature and second positions of a second feature in the target image. The first feature is an outer contour feature of a target object in the target image, the second feature is a feature of an interfering subobject in the target object. The method also includes: determining, based on the first positions, an image region including the target object; dividing, based on the second positions, the image region into at least two detection regions; and determining, according to a pixel value of a target detection region, whether the target detection region meets a preset unoccluded condition, to determine whether the target object is occluded. The target detection region is any one of the at least two detection regions.

Abstract: A multimedia processing method includes rendering, through a first native container node of a dynamic page, a content node associated with the first native container node to play multimedia content. The method further includes generating a non-dynamic page in response to a first page switching operation triggered in the dynamic page, and creating a second native container node in a second node tree of the non-dynamic page, the second native container node being supported by the native application framework provided by the operating system. The method further includes disassociating the content node from the first native container node, and establishing an association between the content node and the second native container node. The method further includes rendering, through the second native container node, the content node in the non-dynamic page to continue playing the rendered multimedia content in a portion of the generated non-dynamic page.

Abstract: This application relates to an image processing method and apparatus, a storage medium, and a computer device. The method includes: obtaining a frequency domain mark image, the frequency domain mark image being obtained by performing frequency domain transformation on a spatial domain mark image; obtaining a transparency parameter configured corresponding to the frequency domain mark image; obtaining target page data; and performing layer superimposition rendering of the frequency domain mark image and the target page data according to the transparency parameter. The solution provided in this application can effectively protect target page data.
